Abstract
A nut includes a body having a neck connected to one end thereof and the neck has a breaking portion formed on the first end thereof. The breaking portion is connected to the end of the body. The thickness of the breaking portion is smaller than that of the neck. A polygonal holding portion is formed to the second end of the neck. The body has a threaded hole defined axially therethrough and the holding portion has a through hole which communicating with the threaded hole. Once the body of the nut is locked to a bolt, the breaking portion is broken and only the body is mounted onto the bolt. The body has a smooth cylindrical outer face.
Description
- 1. Fields of the Invention
- The present invention relates to a nut, and more particularly, to a nut that cannot be removed from the bolt.
- 2. Descriptions of Related Art
- The
conventional nut 10 is disclosed inFIG. 1 and generally is ahexagonal nut 10 and a tool is able to clamp two sides of thehexagonal nut 10 and rotate it so as to lock thenut 10 to anobject 12, or remove thenut 10 from theobject 12. If the users want thenut 10 to be permanently locked to theobject 12 and cannot be removed, at least onewelding spot 13 is applied to the connection portion between thenut 10 and thebolt 11 as shown inFIG. 1 , However, it takes a lot of time to weld thenut 10 to thebolt 11 and this also increases the cost. - The present invention intends to provide a nut that is designed not to be removed from the bolt so as to eliminate the shortcomings mentioned above.
- The present invention relates to a nut and comprises a body having a neck connected to one end thereof, and the neck has a breaking portion formed on the first end thereof. The breaking portion is connected to the end of the body. The thickness of the breaking portion is smaller than that of the neck. A polygonal holding portion is formed to the second end of the neck. The body has a threaded hole defined axially therethrough and the holding portion has a through hole which communicating with the threaded hole. Once the body of the nut is locked to a bolt, the breaking portion is broken and only the body is mounted onto the bolt.
- Preferably, the body has a smooth cylindrical outer face.
- Preferably, the body has a smooth tapered outer face.
- The primary object of the present invention is to provide a nu that is easily mounted to a bolt and cannot be removed from the bolt.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
-
FIG. 1 shows the conventional nut is used to a bolt which extends through two objects; -
FIG. 2 is a perspective view to show the first embodiment of the nut of the present invention; -
FIG. 3 is a cross sectional view to show the first embodiment of the nut of the present invention; -
FIG. 4 is a cross sectional view to show that the first embodiment of the nut of the present invention is mounted to a bolt wherein the holding portion and the neck are not yet separated from the body of the first embodiment of the nut; -
FIG. 5 is a cross sectional view to show that the first embodiment of the nut of the present invention is mounted to a bolt wherein the holding portion and the neck are separated from the body of the first embodiment of nut; -
FIG. 6 is a perspective view to show the second embodiment of the nut of the present invention; -
FIG. 7 is a cross sectional view to show the second embodiment of the nut of the present invention; -
FIG. 8 is a cross sectional view to show that the second embodiment of the nut of the present invention is mounted to a bolt wherein the holding portion and the neck are not yet separated from the body of the second embodiment of the nut, and -
FIG. 9 is a cross sectional view to show that the second embodiment of the nut of the present invention is mounted to a bolt wherein the holding, portion and the neck are separated from the body of the second embodiment of nut. - Referring to
FIGS. 2 and 3 , thenut 2 of the present invention comprises atubular body 20 having aneck 22 connected to one end thereof. Theneck 22 has a breakingportion 23 formed on the first end thereof, and apolygonal holding portion 24 is formed to the second end of theneck 22. Thepolygonal holding portion 24 is a hexagonal holding portion. The breakingportion 23 is connected to the end of thebody 20. The thickness of the breakingportion 23 is smaller than that of theneck 22. Thebody 20 has a threadedhole 25 defined axially therethrough. Theholding portion 24 has a throughhole 26 which communicating with the threadedhole 25. - When in use, as shown in
FIGS. 4 and 5 , abolt 3 extends through anobject 4 and the threaded section of thebolt 3 extends beyond theobject 4. Thenut 2 is mounted to the threaded section of thebolt 3 and thenut 2 is rotated by using a tool holding theholding portion 24. The threaded section of thebolt 3 is threadedly connected to the threadedhole 25 of thebody 20 of thenut 2 when rotating thenut 2. When thenut 2 securely contacts against theobject 4, the tool is continuously rotated, the torque applied to theholding portion 24 breaks the breakingportion 23 because the thickness of the breakingportion 23 is thinner than the rest portion of theneck 22 as shown inFIG. 5 . Theholding portion 24 and theneck 22 are then removed from thebody 20 and the threaded section of thebolt 3. Because thebody 20 has a smooth cylindricalouter face 21 so that no tool can clamp thebody 20 to remove thebody 20 from thebolt 3. -
FIGS. 6 and 7 show the second embodiment of the present invention, wherein the difference between the first embodiment and the second embodiment of the present invention is that thebody 20 has a smooth taperedouter face 27. - Similarly, when in use, as shown in
FIGS. 8 and 9 , abolt 3 extends through anobject 4 and the threaded section of thebolt 3 extends beyond theobject 4. Thenut 2 is mounted to the threaded section of thebolt 3 and thenut 2 is rotated by using a tool holding theholding portion 24. The threaded section of thebolt 3 is threadedly connected to the threadedhole 25 of thebody 20 of thenut 2 when rotating thenut 2. When thenut 2 securely contacts against theobject 4, the tool is continuously rotated, the torque applied to theholding portion 24 breaks the breakingportion 23 because the thickness of the breakingportion 23 is thinner than the rest portion of theneck 22 as shown inFig. 7 . Theholding portion 24 and theneck 22 are then removed from thebody 20 and the threaded section of thebolt 3. Because thebody 20 has a smooth taperedouter face 27 so that no tool can clamp thebody 20 to remove thebody 20 from thebolt 3. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
